Snooki's Wedding Rehearsal = A 'Jersey Shore' Reunion

The gang got back together before Nicole Polizzi's upcoming nuptials.

What's one of the most important parts of every bride's wedding? Her bridesmaids, of course.

Over the weekend -- and just days before their best gal pal's nuptials -- Jenni Farley, Deena Cortese and Sammi Giancola reunited with Nicole Polizzi for a '20s-themed rehearsal dinner in the Garden State. A "Jersey Shore" reunion TOTALLY worthy of a fist pump, if you ask us.

"At rehearsal with my girlies!!!! ❤️ @jennijwowwmtv @deenanicolemtv @sammisweetheart," the soon-to-be Mrs. Jionni LaValle -- who also celebrated her 27th birthday on Sunday -- captioned the adorable pic above on Instagram.

Enjoying the last moments of bachelorette life, the "Snooki & JWOWW" star partied the night away in style, looking stunning in a long white gown as she channeled her inner Daisy Buchanan. Meanwhile, her BFFs looked equally gorgeous in all-black attire.

And like any dutiful and loyal bridal party, Deena and Jenni couldn't help but beam with pride as they counted down the days to their bestie's special day.
